I don't like a single seam down the center of the back or across. I take my 2 panels and sew both edges together with right sides facing and then split one of the panels down the middle. This will give you 2 seams with one on each side. For some reason the seams hold up better if they aren't in the center.

Wow Nana, my thought was to have a center panel to, with the extra panel being split down the middle and attached to each side, I really like your method much better. Guess that is why you are able to make so many "tents" . Over time you have found an easier way to do it. Thanks for enlightening me. (Never too old to learn something new) Ginny

I love this idea! Are your seams vertical or horizontal? Do long-arm quilters like this approach? Does anyone know?
